In answer to my own question,after many phone conversations and forum trawling,the answer did in fact turn out to be the ICU.Now i didn"t discover this, it was in fact a brilliant guy called Stephen at Yamaha UK tech services dept.He spent ages trying to track down the answer so if any of you have a question,give him a bell.I"ve managed to source a used Brit spec ICU which hopefully should be here soon,so as soon as that comes and I get my cylinder head de-carbonised, I2ll be out playing in the sun again.If for any strange reason, anyone wants a restricted ICU let me know.

hi everyone, in the early 90"s German bikes were restricted on output. I"ve got a 1993 YZF750R bought new in Germany. My question is was this bike restricted through the Ignition Control Unit and will fitting a British spec ICU bring it back to full power.Cheers.

hi people, just joined and have a problem. Does anyone know if a 1993 YZF750R imported from Germany is restricted through the Ignition Control Unit or by some other means, or if at all. Cheers.
